Your point that seat of the pants pressure sensations are used during
instrument flight does not disprove MX's point about the necessity of relying primarily on your instruments for accurate information in IMC. Actually my point does! The fly by the seat of my pants did not feel like I had a 20 to 30 degree pitch up which my horizon indicator showed (which was waaaaaaaaay more then Vx pitch). Again, you're arguing about a different topic -- flight in IMC without a vacuum system. This is often classified as an "emergency", and you must use everything you can to get out of it -- including your "seat of the pants". In normal instrument flight, pilots are trained to ignore what their body is telling them. The fact that you were able to use your body's sensations to escape from a very serious instrument failure is a tribute to your piloting skills. You may also wish to purchase a lottery ticket, because not all vacuum failures end so well. ;-) -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Ignore what your head sez (leans), but not what your seat of your pants (positive or negative G's) And this is normal full panel instrument flying. In IMC, the airplane is just an extension of your body and you get very intimate to what it's trying to tell you. To better equate it to you as a VFR pilot, it is no different then the last 6 inches of flight on landing :-) If you ignore the negative G's in your rear end on landing 6 inches above the runway, you will come down with a thump. If you feel too much positive G's in the seat of your pants on landing, you will float. When you hit that sweet spot between the two, you won't even know the wheels touch terra firma. Instrument flying is no different whether you be in level flight or on an actual approach. The fact that you were able to use your body's sensations to escape from a very serious instrument failure is a tribute to your piloting skills. *You may also wish to purchase a lottery ticket, because not all vacuum failures end so well. I may need that lottery ticket, not for surviving the problem, but the cost of a new regulator! Pump is fine, but the regulator does not appear to be regulating! 1.2 AMU is a preliminary estimate. While I would love to say it's my piloting skills, it really starts with the quality training I received from the get go. I just took my training to heart. |

The change in those sensations might give you some information in the initial instant of change, but after that they are more likely to confuse you to death. And this is the entire point I am trying to drive across. The absence of a sensation is more important then no sensation in an IMC environment. I am not talking about unusual attitudes as it would be too late then, as obviously if you get yourself in an unusual attitude situation, you were ignoring signs WELL BEFORE that happens. I am talking VERY SUBTLE changes that you have to be acutely aware of before it exasperates into an unusual attitude situation which INCLUDES scanning all instruments AND feeling results of power adjustments.. Nowhere am I saying it's a primary decision making process, but if you make an input such as add power, you should feel something in the seat of your pants. If you reduce power, you should feel a negative G type feeling. If you don't, something is radically wrong. It is a TOOL for verifying instrumentation as demonstrated in my Friday situation.. You can't tell me that if you are on an ILS approach and you find yourself sliding below glideslope that by adding power you don't feel it in the seat of your pants AND find that comforting. Add power and then don't get that seat of the pants feeling, you best start looking at instruments, trim settings or more importantly OUT the WINDOW for icing. If you don't feel it, then you really are missing one of the finer tools of flying as IFR flying is not all gauges. All gauge flying can be done on a desktop MSFS. Knock yourself out on that, but that doesn't give you the leans, nor any physiological sensations for control input which is vital to feel in addition to scanning the instruments.. AGAIN, it's a tool to supplement and VERIFY what your eyes do indeed see, not a replacement. All of my postings are toward IA pilots, not VFR pilots. VFR pilots won't have the skills to work a partial panel situation as quickly as a IA pilot and if a VFR pilot finds them in IMC AND a partial panel situation, then they really are having a bad day. IA pilots with a vacuum failure, it is a nuisance but not a life endangering situation PROVIDING they use all their training resources and of course the remainder of the airplane systems are still fully functional. |

Almost as bad as my stupid Piper stall indicator switch -- $1300 back in 1999 money! What a rip...

Jay, good observation here but Al is still wrong. As you probably remember from training you have primary and secondary instruments for climbs, turns, decents, etc. To claim to be able to replace any of these with your superior senses is not correct and a bad habit. In normal instrument flight, pilots are trained to ignore what their body is telling them. Exactly. As you move up in the approach categories this becomes more important because you have much less time between being on course and a full scale deflection. On a A3 Hud you even initiate the flare by a prompt on the combiner. Other than a little bit of control feedback seat of the pants is pretty much out the window. ;-) -- Jay Honeck Iowa City, IA Pathfinder N56993www.AlexisParkInn.com "Your Aviation Destination" |

In normal instrument flight, pilots are trained to ignore what their body is telling them. Not exactly. I was told to understand and be able to recognize various physiological illusions, but I was told NOT to ignore others. For example, if my ears--my body--tell me that the prop or engine is winding up, I might be experiencing a change in power, airspeed or a rapid descent even though the pitot-static instruments are not moving? To extend this logic, if my eyes--my body--tell me that there's a mountain in my way, do I ignore it just because the altitude indicator is stuck on 12,000? If my nose--my body--smells smoke or burning oil but the engine instruments don't show a problem, do I ignore my senses? If all of a sudden I feel like I weigh 500 pounds or an unbelted passenger is floating around the cabin, odds are something isn't right. -c Commercial Pilot, Instrument, ASEL Advanced Ground Instructor |
